# Miscellaneous
|
M1 cut of environment, profiles and property work (SPR-7508)
Decomposed Environment interface into PropertySources, PropertyResolver
objects
Environment interface and implementations are still present, but
simpler.
PropertySources container aggregates PropertySource objects;
PropertyResolver provides search, conversion, placeholder
replacement. Single implementation for now is
PropertySourcesPlaceholderResolver
Renamed EnvironmentAwarePropertyPlaceholderConfigurer to
PropertySourcesPlaceholderConfigurer
<context:property-placeholder/> now registers PSPC by default, else
PPC if systemPropertiesMode* settings are involved
Refined configuration and behavior of default profiles
See Environment interface Javadoc for details
Added Portlet implementations of relevant interfaces:
* DefaultPortletEnvironment
* PortletConfigPropertySource, PortletContextPropertySource
* Integrated each appropriately throughout Portlet app contexts
Added protected 'createEnvironment()' method to AbstractApplicationContext
Subclasses can override at will to supply a custom Environment
implementation. In practice throughout the framework, this is how
Web- and Portlet-related ApplicationContexts override use of the
DefaultEnvironment and swap in DefaultWebEnvironment or
DefaultPortletEnvironment as appropriate.
Introduced "stub-and-replace" behavior for Servlet- and Portlet-based
PropertySource implementations
Allows for early registration and ordering of the stub, then
replacement with actual backing object at refresh() time.
Added AbstractApplicationContext.initPropertySources() method to
support stub-and-replace behavior. Called from within existing
prepareRefresh() method so as to avoid impact with
ApplicationContext implementations that copy and modify AAC's
refresh() method (e.g.: Spring DM).
Added methods to WebApplicationContextUtils and
PortletApplicationContextUtils to support stub-and-replace behavior
Added comprehensive Javadoc for all new or modified types and members
Added XSD documentation for all new or modified elements and attributes
Including nested <beans>, <beans profile="..."/>, and changes for
certain attributes type from xsd:IDREF to xsd:string
Improved fix for detecting non-file based Resources in
PropertiesLoaderSupport (SPR-7547, SPR-7552)
Technically unrelated to environment work, but grouped in with
this changeset for convenience.
Deprecated (removed) context:property-placeholder
'system-properties-mode' attribute from spring-context-3.1.xsd
Functionality is preserved for those using schemas up to and including
spring-context-3.0. For 3.1, system-properties-mode is no longer
supported as it conflicts with the idea of managing a set of property
sources within the context's Environment object. See Javadoc in
PropertyPlaceholderConfigurer, AbstractPropertyPlaceholderConfigurer
and PropertySourcesPlaceholderConfigurer for details.
Introduced CollectionUtils.toArray(Enumeration<E>, A[])
Work items remaining for 3.1 M2:
Consider repackaging PropertySource* types; eliminate internal use
of SystemPropertyUtils and deprecate
Further work on composition of Environment interface; consider
repurposing existing PlaceholderResolver interface to obviate need
for resolve[Required]Placeholder() methods currently in Environment.
Ensure configurability of placeholder prefix, suffix, and value
separator when working against an AbstractPropertyResolver
Add JNDI-based Environment / PropertySource implementatinos
Consider support for @Profile at the @Bean level
Provide consistent logging for the entire property resolution
lifecycle; consider issuing all such messages against a dedicated
logger with a single category.
Add reference documentation to cover the featureset.
